Abstract: Variable Elevator Up Peak Dispatching Interval Abstract A plural elevator system having a group controller for controlling the joint response of a plurality of elevator cars to the needs of a building, employs a microprocessor-based group controller for providing up peak, down peak and other zone-controlled elevator functions.  The group controller provides a variable interval between dispatching of elevator cars from the lobby during up peak, the dispatching interval being controlled by the approximate round trip time of an elevator being dispatched from the lobby in serving the car calls registered within it and re-turning to the lobby, or the average of the approxi-mate round trip time for two or three most recently dispatched elevator cars.  The dispatching interval is determined by the approximate round trip time divided by the number of elevator cars serving the up peak traffic.  In addition, the dispatching interval can be further reduced in dependence upon the number of cars standing at the lobby, the re-duction being greater in case the last car leaving the lobby is not more than half full than in the case when the last car leaving the lobby is more than half full.  Exemplary elevator and microprocessor structure, an overall group controller microprocessor program logic flowchart, illustrative of the environment of the invention, and detailed logic flowcharts illus-trative of an embodiment of the invention are disclosed.

Abstract: Abstract of the Disclosure A unique hydraulic circuit is provided for converting rectilinear motion to rotational motion about an axis through the use of two pivotally mounted hydraulic motors.  The hydraulic motors are pivotally interconnected between a pivoting member and a fixed member.  A source of hydraulic fluid under pressure is directed to each hydraulic motor by a conduit system incorporating a flow control valve and a sequencing valve.  The flow control valve selectively delivers fluid power to the hydraulic motors to rotate the pivoting member in one direction or the other.  The sequencing valve senses the angular position of the two hydraulic motors and redirects the flow of fluid to the hydraulic motors in such a manner as to maintain the torque applied to the pivoting member relatively constant.  The sequencing valve acts to redirect the flow of hydraulic fluid to the hydraulic motors so that only one of the hydraulic motors is pressurized at the end of the arc of swing of the pivoting member.  The other hydraulic motor, at the beginning of the arc of swing of the pivoting member, has pressure applied to both sides of its piston by the sequencing valve. Both hydraulic motors are pressurized by the sequencing valve to develop their maximum output force when those hydraulic motors are between their overcenter positions.

Abstract: Abstract of the Disclosure A structural member having an enlongated body shell, which may be fiber glass, and a pair of end caps enclosing the ends of the shell.  A plurality of bands extend through the shell connecting the caps and pulling them toward each other, thus rigidifying the member and securing the caps.  Contact between the interior surfaces of the shell and the side edges of the bands causes the shell to resist collapse.  At one end of the member, the bands are secured to the end cap by movable anchor piece.  A tensioning member threadedly engages the anchor piece so that tension can be applied to the bands by rotating the tensioning member.  At a predetermined tension, a drive piece connected to the tensioning member breaks away and serrations on the head of the tensioning member prevent it from counter-rotating to release the tension.
